Instructions

Mediterranean Roasted Vegetable Casserole

1. Preheat your oven to 425°F (220°C). Lightly grease a 9×13 inch casserole dish with olive oil.
2. In a large bowl, toss the sliced zucchini, red bell peppers, red onion, cherry tomatoes, and minced garlic with 2 tablespoons olive oil, dried oregano, salt, and pepper.
3. Transfer the vegetables to the casserole dish and spread evenly.
4. Roast in the oven for 25-30 minutes, stirring halfway through, until the vegetables are tender and slightly caramelized.
5. Remove from oven and sprinkle crumbled feta cheese over the top, if using.
6. Return to oven for another 5 minutes until the cheese is slightly melted.
7. Garnish with fresh basil leaves before serving.

Cheesy Baked Quinoa & Veggie Bake

1. Preheat oven to 375°F (190°C). Grease a casserole dish with olive oil.
2. In a medium saucepan, bring vegetable broth to a boil. Add rinsed quinoa, reduce heat, cover, and simmer for 15 minutes or until quinoa is fluffy and liquid absorbed.
3. While quinoa cooks, sauté broccoli, carrots, mushrooms, and garlic in 2 tablespoons olive oil over medium heat until tender, about 7 minutes.
4. In a large bowl, combine cooked quinoa, sautéed vegetables, dried thyme, salt, and pepper. Mix in half of the mozzarella and Parmesan cheese.
5. Transfer mixture to the casserole dish and sprinkle remaining cheese on top.
6. Bake uncovered for 20-25 minutes, until cheese is golden and bubbly.
7. Remove from oven and let rest for 5 minutes before serving.

Spicy Roasted Chickpea & Vegetable Tray Bake

1. Preheat oven to 400°F (200°C). Line two baking sheets with parchment paper.
2. In a large bowl, combine chickpeas, cubed sweet potatoes, red onion wedges, and red bell pepper slices.
3. Add olive oil, smoked paprika, cumin, cayenne pepper, salt, and black pepper to the bowl. Toss until everything is evenly coated.
4. Spread the mixture in a single layer across both baking sheets.
5. Roast for 30-35 minutes, stirring halfway through, until chickpeas are crispy and vegetables are tender.
6. Remove from oven and garnish with fresh cilantro before serving.

Tips & Variations

“Don’t overcrowd your baking sheets to ensure crispiness and even roasting.”

Feel free to swap vegetables depending on seasonality or preference. For example, substitute sweet potatoes with butternut squash or add eggplant to the Mediterranean casserole for extra depth.

You can also make the quinoa bake vegan by omitting cheese or using plant-based alternatives.

Try adding fresh herbs like rosemary or thyme to the roasted chickpea tray for an aromatic boost. For a sweeter twist, drizzle a little honey or maple syrup over the Mediterranean veggies before roasting.

If you want to prepare these dishes ahead of time, both casseroles reheat wonderfully in the oven or microwave, making them perfect for meal prep.
